Can I use the JavaScript Calendar library with other web development frameworks?

Yes, many JavaScript calendar libraries are designed to work with a variety of JavaScript frameworks like React, Vue JS, and Angular.

Does JavaScript need CSS to create a calendar?

No, JavaScript does not necessarily need CSS to create a calendar, but CSS can be useful for styling and formatting the calendar’s appearance. You can use JavaScript to dynamically generate the HTML elements and content that make up a calendar, such as the month, days, and events.

Criteria for a Good JavaScript Calendar Library.

1) Documentation

Documentation plays a very crucial role when selecting any library or framework. It helps you understand the library and simplifies its usage, saving you a lot of time.

Good documentation often includes sample codes, user guides, live demos, and tutorials, which kickstart projects without any issues. Every developer uses documentation because instead of figuring out the code themselves, they prefer using documentation to make their development easier.

2) Performance

The performance effect of a JavaScript Library on any web application is very important. If you are using a heavy JavaScript Library then it will indirectly affect your web page loading performance and visa-versa.

Hence, make sure you use performance testing tools like Lighthouse while using a bigger JavaScript library on your web page. I would prefer to opt for a smaller alternative if it offers more functionality.

3) Customization

If you are using a library that has more customization options then it can help you to give more variation and unlimited changes. Sometimes, you might have faced exceptional changes in your projects like changing the design, removing and adding functions, typography, etc.

Therefore, if you are using a customizable library that is easy to customize then you will not face any problems.

4) Compatibility

If your calendar app can work only on selective browsers and devices, it shows that your library is not compatible enough to work on every platform. Hence, the compatible criteria say that you need to make sure, that it works across all types of devices and all the major browsers.

5) User Experience

User experience is also important when you are choosing a calendar library. It should be easy to understand, simple design structure, and be visually appealing.
